STRENGTHS

• Effective and highly customisable process;
• Quick product change;
• High reliability;
• Low maintenance and access from outside to machine components;
• Easy installation in small spaces.

TECHNICAL FEATURES
The new rotary cooler dryer, which has been completely redesigned in its construction, is developed vertically in a modular manner.
In standard sizes, cylindrical modules are available in diameters of 2.2, 2.5 and 2.8 metres and range from a minimum number of 3 up to 8.

Each module consists of:

• Outer ring consisting of press-folded flanged panels that can be completely dismantled, equipped with an access hatch on the inside and inspection hatches;
• Impeller consisting of a flanged rotating shaft and product support plane, made up of self-cleaning circular tilting sectors in slotted sheet metal;
• Product layer levelling device;
• Safety and product passage control sensors to ensure rapid product change.

The drive consists of a geared motor, safety coupling and gearbox directly keyed to the machine shaft.
The rotation speed, variable via an inverter, allows the treatment time to be adjusted.

At the base of the machine is the inlet module for cooling air, in the centre the inlet module for hot air, which is suitable for drying the product.
In order to achieve high drying temperatures, the two air flows can be regulated by a by-pass system on request.

OPERATION
The product is loaded from above and as it passes through the various stages it is hit by the countercurrent air flow.

The first modules are dedicated to drying, the last to cooling.
Thanks to the uniformity of the layer and the tilting that the product undergoes as it passes from one stage to the next, the drying and cooling process inside the Fragola rotary cooler dryer is particularly effective.

At the base of the machine is the inlet module for cooling air.

OPERATION
The product is fed from above and by means of the tilting sectors of the various turntables is gently tipped from plane to plane until the cooler is unloaded.
At the same time, countercurrent air is sucked in from the base module at room temperature.
The progressive cooling of the product with a low temperature difference between the air and the product itself allows a reduction in relative humidity without condensation.
Thanks to the uniformity of the layer and the tilting that the product undergoes as it passes from one stage to the next, the cooling process inside the Fragola rotary cooler is particularly effective.

Available capacity from 5 ton/hour to 50 tons/hour, specific gravity of 0.6 tons / m3.

OPERATION

The product is dosed into the cooler through a rotary feeder and is cooled by counterflow air flow. Cooling takes place gradually until the product is discharged into the collecting hopper.

Various unloading systems are available to ensure product integrity.

Cooling time from 8 and 10 minutes.

ROTARY SIEVE CRYLOC VR 15 / VR 22 / VR 27

The range of models of the VR – Cryloc Rotary Sieve goes from a production capacity of 20 ton/h up to 120 ton/h, with a specific weight of 0.6 ton/ m3, with diameter from 1500 mm to 2700 mm.

FEATURES

Compact machine with minimal space requirements
Product layer levelling device adjustable from the outside
Emergency inspection hatch

OPTIONS

Handling system with sliding on rails for cryloc: with this system the cryloc is able to receive product from a whole series of silos.
Application of pneumatic dust extraction and conveying system in a special recovery line.

Their very strong construction, the improvements made in the course of time, and the easy replacement of sieves, contribute to the high reliability and efficiency of this machine. The body is wholly reinforced and made of hot-drawn bolted elements of press-bent sheet. It rests on the support frame by means of iron springs, and this arrangement eliminates the transmission of vibrations to the screen housing level.

The motor-vibrators are fastened to the body and to a draw piece connecting the block. Sieves are made of music wire grid, anchored on the head and stretched by tail tie rods. The adjustment of sieves, as well as their easy and quick replacement, is carried out externally.

The screens can contain 1, 2 or 3 sieves in order to obtain 2, 3 or 4 different gradings of the product respectively. To increase the produttive capacity of a screen, 2 equal-mesh sieves can be assembled in parallel, with an intermediate grading bottom, thus obtaining 2 fractions of product.
